Decora unit mounting

The HDMI 201 A D (Decora) transmitter and receiver can be installed in a one-gang electrical wall box with a Decora wall plate cover (supplied).

The installation must conform to national and local electrical codes and to the wall plate’s size requirements.

UL/safety guidelines

The following Underwriters Laboratories (UL) guidelines pertain to the installation of the Decora transmitters and receivers into a wall or furniture.

1. These units are not to be connected to a centralized DC power source or used beyond their rated voltage range.

2. These units must be installed in UL listed junction boxes.

3. These units must be installed with conduit in accordance with National Electrical Code.

Preparing the site and installing the wall box

Choose a location that allows cable runs without interference. Allow enough depth for both the wall box and the cables. The box should be at least 2.5" (6.4 cm) deep to accommodate the connectors and cables. Install the cables into the wall, furniture, or conduits before installing the wall plate.

NThe Decora units are very deep and have connectors on the back side (figure 2-9). Extron recommends its 1-gang or 2-gang junction boxes (part #s 980130 and 980084), which have a depth of 2.5" (6.4 cm).
